I tried to find some specific information, but in vain. We should ask Batgirl, ( beyond praise ) she might know a lot more ! Thanks !!!
This is what I found in three reference books :
Botvinnik founded " his own school " in 1963, and he became a leading member of the Soviet Coaching System, that enabled the Soviet Union to dominate top-class chess during that time.
He assisted with the training of younger Soviet players, earning him the nickname of " Patriarch of the Soviet Chess School ".
He was still playing a major teaching role in his late 70s, when Kramnik and Shirov entered " the " school.
I found nine names of pupils, Balashov, born 1949 and 1st success 1969; Karpov, born 1951, 1st success 1969; Dolmatov, born 1959, 1st success 1978; Yusupov, 1960, succ 1977; Ehlvest born 1962; Kasparov, born 1963, 1st success in 1980 -- and Akopian, born in 1971.
Kramnik and Shirov are born in 1975 ( Botwinnik, 1911-1995, was 64 at that time. I wonder what role Botwinnik played for them, taking into account their first successes around 1990-1995.
You mention elite and academy and legendary, the truth can be different, I don't know, but I am as curious as you are, Botvinnik being such an important person in our Chess history ! I hope "will be continued" !
I think most of us here probably have heard of the legendary chess school set up by Mikhail Botvinnik. Does it still exist today? Or was it shut down after the collapse of the Soviet Union?
